A couple of minor notes.  Strike's brew is "Phycoplonk".  :-)

As potent as we may assume Phycoplonk to be, the correctness of
the solution does depend on the rather obvious assumption that
a penny SINKS in a glass of Phycoplonk as it does in a glass of
water.  :-)  NOW you have all the ingredients to tackle this
physics problem that is fundamental to the physics of scuba.
